［摘要］随着国民经济的发展和建筑技术的进步，大跨度悬挑钢结构工程的应用越来越多。而高抗震设防烈度下的大跨度结构的设计一直是结构工程师关心和探讨的课题。通过PKPM软件对箱形悬挑钢结构平台进行建模分析，结构的应力比、挠度、位移等计算指标的计算结果满足规范要求。此外，抗震构造措施的进一步加强，确保了该结构设计的安全与可靠。

Abstract: With the development of the national economy and the progress of architectural technology, more and more steel structure engineering of long span suspension are applied. That the engineers always care about and discuss is the design of large span structure under seismic fortification intensity. The model was built by PKPM software to analyze the box type cantilever steel platform, and calculation results of calculation parameters including the stress ratio, deflection, displacement, and so on, can meet the requirements of specification. In addition, the anti-seismic measures were adopted to ensure the safety and reliability of the structure design.

Keywords: overhanging steel structure; box; deflection; displacement
